Show original supplier description
The TransGo SK A650 SHIFT KIT® Valve Body Repair Kit is engineered to resolve common issues in the 1998-2005 Lexus A650E 5-speed automatic transmission. Complaints such as shuttle shifts, bind-up or flare during the 2-3 shift, and slips in 3rd or 4th gear can be mitigated by this kit. It also targets solenoid and TCC performance codes and rough kickdown caused by slow TCC release. Key areas of concern addressed by this kit include wear in the TCC relay boost valve and bushing, which prevents proper control of the lock-up clutch, and wear in the solenoid modulator valve bore. The kit provides a USA-made hardened steel TCC relay boost valve and bushing to restore hydraulic circuit integrity. Additionally, a redesigned, drop-in solenoid modulator valve system, along with its furnished bushing and spring, restores proper function without requiring special tooling. This kit corrects and prevents issues including shuttle shifts, 2-3 shift bind-up or flare, slips under throttle in 3rd/4th gear, and rough kickdowns. It can also help resolve diagnostic trouble codes such as P0746, P0751, P0756, P0771, P0776, P0894, P2714, and P2757. The included components are a USA-made hardened steel TCC relay boost valve, bushing, and retainer, as well as a USA-made hardened steel solenoid modulator valve, bushing, spring, and end plug. A 0.055” drill bit is also included for installation.
